This disclosure provides compositions and methods for delivering a viral composition to cells, e.g., for cell surface receptor-mediated uptake, and enhanced viral transduction. Viral transduction can be achieved via a modified viral composition that includes a moiety that binds to a cell surface receptor ligand. Modified viral compositions and methods for reducing levels or titers of neutralizing antibodies in a subject in need of viral therapy, e.g., gene therapy, are provided. In some embodiments, the modified viral composition includes empty viral particles that bind and internalize neutralizing autoantibodies. Modified viral compositions including empty viral particles can be administered prior to viral therapy. Also provided are pharmaceutical compositions and kits including a modified viral composition. |
